The Allegro Network Multimeter can be configured to use a time synchronization service. NTP is supported for all variants of the Multimeter, PTP service may be used if management interface supports hardware time stamping.
The Allegro Network Multimeter can be configured to use a time synchronization service. NTP is supported for all variants of the Multimeter, PTP service may be used if management interface supports hardware time stamping.
In case a GPS capable PTP grandmaster card is available, GPS time synchronization is available and the antenna cable delay in nanoseconds can be configured.

To enable a time service, switch to the proper type in the dropdown box.

The time service field will show whether the selected service is running or not.

For NTP time retrieval you can specify and edit dedicated NTP servers. If you do not specify a NTP server, a set of predefined NTP servers will be taken automatically.

For PTP time retrieval, the PTP grandmaster clock identity is shown. This is usually an EUI-64 address.
The first and last set of octets of the identity represent the (EUI-48) MAC address of the grandmaster.


If L3 tunnel mode is enabled for an interface this interface will only process packets encapsulated in GRE or

GRE+ERSPAN and targeted for the configured IP address. All other packets received on that interface will be
 
discarded. The system will process the packets as if only the inner encapsulated packet is seen and any traffic
captures will only contain the encapsulated packet. An interface with L3 tunnel mode enabled will respond to
ARP requests and to ICMP echo requests so it is possible to use ping to verify that the interface is reachable un-
der the configured IP address. Currently only IPv4 L3 tunnels are supported. It must be noted that if the system
is running in bridge packet processing mode any links with an interface configured for L3 tunnel mode will not
forward traffic.
Following settings are possible for PTP and should match to the settings of the PTP grandmaster:
